CHARLES H. TRASK, OF LYNN, MASSACHUSETTS, ASSIGNOR TO THE DUPLEX SHOETRIMMER COMPANY, OF PORTLAND, MAINE.

SPECIFICATION forming part of Letters Patent No. 380,609. dated April 3,1888.

Application filed June 8, 188?. Serial No. 240,597. (No model.)

To aZZ whom it may concern.-

Be it known that 1, CHARLES H. Teams, of Lynn, in the county of Essexand State of Massachusetts, a citizen of the United States, haveinvented a new and useful Improvement in Boot or Shoe Sole TrimmingMachines, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, forming apart of this specification, in explaining its nature.

The invention relates especially to a soleedge-trimming machine having arest for the edge of the sole especially adapted for use in trimming theheel-edge of spring-heels. It is represented as organized in a duplexsole-edgetrimming machine, although it may of course be used in amachine having only a single soleedge trimmer.

The invention further relates to various features of construction andorganization, all of which will be hereinafter described.

In the drawings, Figure l is a view in end elevation of the head of aduplex machine having the features of my invention. Fig. 2 is a view inplan thereof. Fig. 3 is a view of the front, to the left of the endshown in Fig. 1. Fig. 4 is an enlarged sectional detail, to whichreference will hereinafter be made.

In the drawings, A is the head of the machine.

a is a shaft supported by the head A, having the pulley a,, carrying atone end a right shankedge trimmer, B, and at its opposite end the leftshank-edge trimmer, B.

c is a shaft, also supported by the head A, having a pulley, 0, arrangedto extend at each end beyond the fronts a a of the head A, and

carrying at one end the sole-edge trimmer O,

set as a right trimmer, and at the other end a sole-edge trimmer G, setas a left trimmer.

The shank and sole-edge trimmers represcnt ed are of the duplex variety,and each soleedge trimmer is covered in part by a hood, D, which ismovable toward and from it upon the shaft 0. It is formed upon the endof the long sleeve d, and this sleeve has a bracket, (2", which extendsupward and is secured to the end of the rod (1 (see Fig. 4,) so that thesleeve d is prevented from being rotated on the shaft 0. The bracket (1also supports the oil-cu p (P,

and there is formed in the bracket 2. channel or passage, 01*. from thecup to the bearing on the shaft 0. The sleeve and the bracket aremovable horizontally upon the shaft 0 and rod d, respectively, and aspring, (i surrounding the shaft 0, bears against the shoulder (2thereon and against the end (2 of the sleeve, and acts in opposition toany movement communicated or given the hood D away or back'from thecutter which it covers, such a movement, for instance, as is given bythe work for the purpose of uncovering or exposing a section of thecutter.

There is supported by the sleeve d and bracket cl, bymeansofthedownward-extending arm 6 and the lower section or portion, 6,of the hood D, which has a hole, 6', the sole-edge rest E. The hood Dhas a hole, e", through which the rest E extends, and the arm 6 also hasa hole, e", for receiving the inner end of the rest. This rest islocated below the trimmer and a little in advance of a vertical linedrawn through its center, (see Fig. 3,) and it serves as a support uponwhich the edge of the sole is steadied and rested while the heel endthereof, or a spring-heel, is being presented to to the trimmer. It isused, as a rule, only during the trimming of this part of the boot orshoe; but of course I do not confine myself to such use. It is madehorizontally movable and horizontally adjustable in its supports, in

order that it may be moved entirely back from the face e of the hood D,and also so that its extent from the face 6* may be varied. Both thehorizontal movement and the adjustment are obtained by providing the rodE with a screw-thread, c and by the nuts e 6 which fit thescrew-threaded section of the rod and are adapted to be turned thereonagainst the arm 6 to lock the rest in place. When the rest is moved backand out of the way, it allows the surface 6 of the hood D to be used asa fingerrest, as described in my Patent No. 357,743.

Having thus fully described my invention, I

claim and desire to secure by Letters Patent of 5 the United States- 1.The combination,in a sole-edge-trimming machine, of a rotary sole-edgetrimmer, and a sole-edge rest, E, arranged in relation to said trimmerto act as a support or rest for the edge ICO of the outsole, and adaptedfor use in the trimming of the heel end of outsoles and springheels, asand for the purposes described.

2. The combiuation,in a sole-edge-trimming machine,ofa rotary trimmer,the horizontallymovable hood or piece D, and a sole-edge rest, E,extending horizontally outward from the face e of said hood or piece D,as and for the purposes described.

3. The combination, in aheel-trimming mamachine, of a rotary sole-edgetrimmer, the sole-edge rest E, and means, substantially as specified,for moving the same into and out of operative position, substantially asdescribed.

4. The combination,in a sole-edge-trimmin'g machine, of a rotarytrimmer, the hood or piece D, formed upon the end of a sleeve, d,

which is movable upon the shaft carrying the rotary trimmer inopposition to a spring, the bracket d, the rod (1 and the arm 6, havinga hole, 6 the hood or piece D, having a hole, 6 and the sole-edge restE, extending through said holes 6 e to beyond the face e of the hood orpiece D, as and for the purposes described.

5. The combination of a rotary trimmer, the hood or piece D, having thehole 6, the arm 6, having the hole 6 and the rest E, having ascrew-threaded section, 6 and nuts 6 6, substantially as described.
